One day in the beginning of one of the breastfeeding classes as I was getting ready to start, one of the consultants approached me and asked why I was wearing a underwired bra. At first I didn't understand her question. She then proceeded to explain that it is generally not recommended for a nursing mother to wear an underwired bra because they have a tendency to cause PLUGGED DUCTS!!!!! Who would have thought it? Definitely, not me .
After that day, I never put them on again and never got a plugged duct again !
